Description
146508146508
Den foreliggende opfindelse angår en fremgangsmåde til forebyggelse af vækst af alger og lav på porøse uorganiske bygningsmaterialer såsom beton, tegl og eternit ved først at behandle bygningsmaterialerne med en vandig opløsning af et kobbersalt og derefter 5 med et bindemiddel, som binder kobberforbindelser i bygningsmaterialerne .The present invention relates to a process for preventing the growth of algae and low on porous inorganic building materials such as concrete, brick and etherite by first treating the building materials with an aqueous solution of a copper salt and then with a binder which binds copper compounds into the building materials.
Det er kendt, at kobberforbindelser er giftige for alger og lav og kan anvendes til at beskytte porøse uorganiske bygningsmaterialer mod vækst af alger og lav. Det er således kendt at imprægnere porø-1° se bygningsmaterialer med kobbersulfat og at imprægnere bygningsmaterialer først med et opløseligt kobbersalt og derefter med et bindemiddel, som udfælder uopløselige eller tungtopløse-lige kobberforbindelser i bygningsmaterialerne.It is known that copper compounds are toxic to algae and lichens and can be used to protect porous inorganic building materials from the growth of algae and lichens. Thus, it is known to impregnate porous-1 see building materials with copper sulfate and to impregnate building materials first with a soluble copper salt and then with a binder which precipitates insoluble or heavily soluble copper compounds in the building materials.
Virkningen af de kendte fremgangsmåder er imidlertid dårlig eller 15 ret kortvarig, hvorfor der er et behov for fremgangsmåder, soro kan give en langvarig virkning.However, the effect of the known methods is poor or rather short-lived, so there is a need for methods that soro can produce a long-lasting effect.
Det har nu vist sig, at en ønsket langvarig virkning opnås med fremgangsmåden ifølge opfindelsen, som er ejendommelig ved, at der som bindemiddel anvendes en opløsning af en højere fedtsyresæbe. Det 20 antages, at der herved bevirkes dannelse af kobberforbindelser af en sådan moderat opløselighed, at giftvirkningen holder sig længe i modsætning til, når der udfældes uopløselige kobberforbindelser.It has now been found that a desired long-lasting effect is achieved with the process of the invention, which is characterized in that as a binder a solution of a higher fatty acid soap is used. It is believed that in this case the formation of copper compounds is of such moderate solubility that the toxic effect persists for a long time as opposed to the precipitation of insoluble copper compounds.
Fremgangsmåden ifølge opfindelsen er effektiv ved påføring af behandlingsopløsningerne ved simpel påstrygning, og er derfor 25 anvendelig til allerede opførte konstruktioner, men kan naturligvis også udføres ved at neddyppe de enkelte stykformede bygningsmaterialer i behandlingsopløsningerne før materialernes anvendelse. Fremgangsmåden medfører ikke dannelse af mørktfarvede kobberforbindelser og er derfor også anvendelige til lyse 30 bygningsmaterialer såsom betonflader.The method according to the invention is effective in applying the treatment solutions by simple application, and is therefore applicable to already constructed structures, but can of course also be carried out by immersing the individual unitary building materials in the treatment solutions before using the materials. The process does not result in the formation of dark-colored copper compounds and is therefore also applicable to light 30 building materials such as concrete surfaces.
Når fremgangsmåden anvendes til fjernelse af en eksisterende begroning af alger og lav, påstryges behandlingsopløsningerne på samme måde som ved behandling af nye bygningsmaterialer.When the method is used to remove an existing fouling of algae and lichens, the treatment solutions are applied in the same way as in the treatment of new building materials.
Derved dræbes begroningen og mister sit fæste i bygningsmate-35 rialet og falder af, således at bygningsmaterialets oprindelige 2 146508 .· farve genskabes* Hvor det drejer sig om udendørs bygningsværker, ...hjælper regn.:til at skylle den dræbte begroning af.Thereby the fouling is killed and loses its attachment to the building material and falls off, thus restoring the original material of the building material * color * In the case of outdoor buildings, ... helps rain: to flush the killed fouling off.
Fremgangsmåden udføres ifølge opfindelsen fortrinsvis med kon-centrede opløsninger af henholdsvis kobbersaltet og sæben, idet 5 en enkelt behandling med hver opløsning i så fald er tilstrækkelig til at give en langvarig virkning.The process according to the invention is preferably carried out with concentrated solutions of the copper salt and the soap respectively, in which case a single treatment with each solution is sufficient to give a long-lasting effect.
- Opfindelsen illustreres nærmere af følgende eksempler.The invention is further illustrated by the following examples.
Eksempel 1Example 1
Etemitplader til en tagbeklædning blev først ved påstrygning be-. handlet med en koncentreret vandig opløsning af kobbersulfat og 10 derefter, ligeledes ved påstrygning, med en koncentreret opløsning af brun sæbe (kaliumsæbe). Etemitpladerne blev oplagt som tag på et beboelseshus i 1960, og i 1979 konstateredes det, at - taget var praktisk taget fri for lav og havde beholdt eternit-' pladernes naturlige farve næsten uændret. Dette er ensbetydende 15 ’ med en meget forlænget begroningshindrende virkning sammenlignet med kendte fremgangsmåder, hvor varigheden af virkningen måles i måneder eller ganské få år.Etemite sheets for a roof covering were first applied by ironing. traded with a concentrated aqueous solution of copper sulphate and then, also by ironing, with a concentrated solution of brown soap (potassium soap). The etemite plates were laid as roofs on a residential building in 1960, and in 1979 it was found that - the roof was practically free from low and had retained the natural color of the eternite plates almost unchanged. This is equivalent to 15 'with a very prolonged antifouling effect compared to known methods where the duration of the effect is measured in months or quite a few years.
Eksempel 2Example 2
Et eternittag oplagt i 1962,og som i 1972 var mørkt af begroning af 20 lav, blev behandlet ved påstrygning først med en koncentreret opløsning af kobbersulfat og derefter med en koncentreret opløs-' ning af brun sæbe. Efter behandlingen døde laverne og regnede efterhånden af, og ved en bedømmelse i 1979 havde taget stadig eter-nitpladernes naturlige grå farve og var uden begroning.An eternite roof laid in 1962, which in 1972 was darkened by fouling of 20 layers, was treated by ironing first with a concentrated solution of copper sulfate and then with a concentrated solution of brown soap. After treatment, the lichens died and eventually rained, and in a 1979 assessment, the ether-rivet plates' natural gray color was still and were without fouling.
Eksempel 3 25 En lodret flade på en gammel betonbro, der var tilgroet med sorte, 2 brune og gule alger og laver, blev indenfor et område på ca. 1 m behandlet ved påstrygning først med en koncentreret opløsning af kobbersulfat og derefter med en koncentreret opløsning af brunExample 3 A vertical surface of an old concrete bridge, overgrown with black, 2 brown and yellow algae and lichens, became within an area of approx. 1 m treated by ironing first with a concentrated solution of copper sulfate and then with a concentrated solution of brown
